Alex Lakatos is a partner in the Washington DC office of Mayer Brown’s Litigation & Dispute Resolution and Financial Services Regulatory & Enforcement practices. Alex practices in complex international litigation, particularly on behalf of non-US financial institutions. He also counsels financial institutions on banking and securities regulatory, enforcement, legislative, and strategic issues. He has significant experience in matters where these areas intersect – for example, the litigation of cross-border disputes in US court in tandem with a DOJ, OFAC or bank enforcement investigation. His matters often include parallel litigation in non-US forums. He is experienced in contesting issues of particular concern to non-US financial institutions, such as financial privacy, data protection, multi-jurisdictional discovery, choice‑of-law conflicts, sanctions compliance and asset forfeiture.

In addition, Alex advises clients on avoiding litigation and provides related regulatory advice in areas such as the USA Patriot Act, the Bank Secrecy Act, the Unlawful Internet Gambling Enforcement Act, anti‑money laundering compliance, and OFAC sanctions. He frequently has assisted clients with internal investigations, particularly related to the aforementioned areas. He has represented clients as both plaintiffs and defendants, in state and federal courts throughout the country and abroad, in class actions and other controversies, on issues including securities fraud, breach of fiduciary duty, breach of contract, civil RICO, the Anti-Terrorism Act, federal jurisdiction and venue.

Alex was recognized as a "Client Service All-Star" reported by BTI Consulting Group. BTI commended its winners for their "commitment to client service and ability to surpass the needs and expectations of the worlds most demanding clients" and lauded them for "standing above all others in the eyes of their clients." Alex is also recommended by Legal 500 and noted as an “'excellent communicator' who specialises in advising foreign financial institutions in enforcement actions and litigation.”

Alex is a member of the firm’s US Consumer Financial Protection Bureau (CFPB) group and co-chair of the firm’s Pro Bono Committee.
